Firmware Updates for Mac mini, MacBook, and 13-inch MacBook Pro

by Agen G. N. Schmitz

Apple has released a trio of similar updates for the following mid-2010 models: Mac mini EFI Firmware Update 1.5 [1], MacBook EFI Firmware Update 2.1 [2], and MacBook Pro (13-inch) EFI Firmware Update 2.5 [3]. Each of these updates enables Lion Recovery from an Internet connection (and all of them require Mac OS X 10.7.2 or later). Additionally, the Mac mini EFI Firmware Update 1.5 fixes an issue with the setting for restart after a power failure. As with any firmware update, you should read the installation instructions carefully before installing. To ensure you get an update only if it’s necessary, we recommend relying on Software Update; if an update doesn’t appear for you, it’s not appropriate for your Mac. (Free, 3.1 MB)
